BOOKBINDING DEVICE.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed July 3, 1914. Serial No. 848,840.

T 0 all whom it may concern:

Be it known that I, GEORGE H. JENKINS, a citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Bookbinding Devices, ofwhich the following is a specification. v

This invention relates to a device for binding in a convenient formloose leaves, c0rrespondence papers, etc, and is concerned with theparticular design and arrangement of the mechanism by which the bindingoperations are carried into effect.

Among the principal objects of my invention, is the provision of meansfor retaining a. stack of leaves in convenient position for treatmentpreparatory to binding; means for adjusting the device to papers ofdifferent size; and means for conveniently handling a stack of leaves inthe various positions required. The invention further consists innumerous other features of construction and combinations of parts aswill more fully hereinafter appear.

In the drawings:

Figure l is a perspective view of a device for alining and evening astack of leaves preparatory to binding;

Fig. 2 is a plan view of the device in which the papers are bound;

Fig. 3 is a side elevation of the device;

Fig. d is an end elevation of the same;

Fig. 5 is a side elevation of the device with one section swung intovertical position; and r Figs. 6 and 7 are detail views of the lookingmeans employed for the movable evener on the device.

Preparatory to binding leaves or papers, it is desirable to even up andaline the edges to bebound. For this purpose, a convenient device isshown in Fig. 1, representing a box-like structure having side walls 8and 9 disposed at right angles to each other, and a base disposed atright angles to each of said walls. For convenience in manipulation, thebase 10 is shown obliquely inclined, and the sides 8 and 9 are tiltedcorrespond ingly. In carrying into eflect the present invention, Iprefer to utilize a strap 11 of any suitable material, such as. webbingor tape, to tie around covers 12 and a stack of leaves 13 between thesame. The use of such tying means is not, however, essential. Slots letare shown arranged in the base and in.

one of the side walls, within which such a strap may lie, therebypermitting leaves to he squarely against the walls of the struc ture.

After alinement has been effected, the paper is transferred to thebinding device which constitutes the substance of my pres ent invention.As shown in Fig. 2, this comprises a base member 15 which for purposesof use should preferably be secured to a fixed base or table 16, and aswinging base member 17 joined to the member 15 as by a hinge connection18. In Fig. 5 is shown the relative positions of the members 15 and 17when a swinging movement has been executed, one or more links 19pivotally secured to one member as at 20 engaging with a pin 21 on theother member to maintain the parts of the base in such right angularrelation when desired.

The leaves when placed upon the portion 17 are alined in longitudinalposition for binding by means of a movable evener 22 which I prefer toconstruct of two telescoping parts to enable leaf stacks of varyingthicknesses to be accommodated. Preferably the upper edge of this eveneris provided with forwardly extending portions to engage with the uppersurface of the stack of leaves undergoing treatment. As appears best inFig. 6, the ends of the evener 22 extend downwardly to provide arms 23which partly overlie the sides of the base. These arms each terminate inan elongated portion 24 which is parallel to the base, and carry aninturned member arranged to lie within a groove or slot 26 formed in theside wall of the base. A ratchet bar 27 is provided on the inner side ofthe groove 26 with which a catch 28 of spring material engages,

the catch being mounted on the elongated portion 2% of the arm 23. Thisconstruction insures a maintenance of the evener 22 in constant verticalposition with provision for adjustment forwardly or rcarwardly on theportion 17 of the base.

Near the swinging edge of the base member 17, I have provided acompression device which, for purposes of illustration, is shown asconsisting of two posts 29 exteriorly threaded to receive a thumb screw30, a. compression plate or bar 31 being arranged to move upon the postsand be guided thereby. The operation and con struction of thiscompression device is quite similar to that shown and described in mypending application, Serial No. 837,5?99, filed May 11, 1914, so thatfurther description 15 not deemed necessary. For the salre or"convenience, these posts should be attached to the base member 17 at theextreme side edge thereof, or if'preierred at places 32 which extend outbeyond the sides of said member to leave as wide a space as possible forpaper leaves to lie therel etween. l have also provided. a second evener33, operating in a di rection transv to the e-vcner 29, and having anarm 3% arranged to engage with a rack 85 disposed within a groove in themember 17. This feature ofconstruction is also disclosed in my pendingapplication referred to.

To the swinging edge of the base member 17, as through the medium ofthumb screws 36 is removably secured member 3? er tending vertically andparallel to the evener 22. This member is formed with a horizontalportion 38 which lies in substantially the same plane with the topsurface of the base members. The vertical portion of the member 37 isslitted as at 39 from the top edge thereof down to and through thehorizon portion thereof, the slits being obliquely inclined in ahorizontal plane to to m, in effect,,a miter plate, as best shown in, 2.That portion of the member 3'? which lies in juxtaposition with theswinging edge of the member 17 is integral from end to end clearlyappears in Fig. 4-.

The bindingoperation, as contemplated in the device herein disclosed,takes place substantially as follows: A stack of leaves first alined,and tied if preferred, are arranged upon the base member 17 with theedge to be bound in square engagement with the member 3?; Should theleaves when laid in position require further alinement, the eveners 22and 33 are adjusted for this purpose. It is, of course, usual inoperations of this kind for toe leaves to be bound be tween suitablecovers, and it is expected, therefore, that covers should be soarranged. While in this position, the thumb screws 30 are manipulated tobring the'bar or plate 31 down upon the stack of leaves with greatpressure, thereby facilitating the further binding operations required.

The base member 17 is next swung around into vertical position asappears in Fig. 5, the link 19 engaging with the pin 21 to lock themembers 15 and l? in iiXed relative positions. Oblique cuts or slits arethen made in the edges of the leaves in the planes determined by theslits 39, through the use or a saw or other suitable device. Thehorizontal portion 38 of the member 37 for this operation functions, asa miter plate, and determines the angle at which the slits shall be cutas well as the depth thereof. The member 37 is next detached from thebase member as its presence no longer is i'etpiired,

the pressure eiiected through the bar 31 is relieved, and the evener 22is advanced to raise the stack into more convenient operating position.

To complete the binding operation, several additional steps arecontemplated which may, however, in practice be modified according tothe requirements of use. Among these is the application of a heavy pasteor glue which has both adhesive and filling properties over the edges ofthe leaves and in the slits'which have been cut therein. A suitable cordor string is then passed through the saw cuts and tied to bind the edgesof the leaves in permanent form. l he saw cuts have been described asdisposed at an angle to prevent displacement of a tying cord, but it isobvious that the same may be parallel and perpendicular to the edge inwhich they are out without in any way impairing the ethciency of the ting means used.
